As shown in Figure 1; The present invention is when work; Anchor pole 11 moves with the anchor pole 11 parallel directions of arrow in the Fig. 1 of the traction lower edge of hauling machine; The reason silk of existing operation be in the middle of dried glass fiber bundle 1 (not soaking the glass fiber bundle of resin) is arranged in as the core silk, the kiss-coating glass fiber bundle 2 that soaked resin is arranged in dried glass fiber bundle 1 uniformly around synthetic one constitute glass fiber bundle.The present invention is twined layer of plastic film on the glass fiber bundle that synthesizes one.
Specific practice is: a supply disk 5 is installed on rotating disk 3; Be tied with plastic tape 8 on the supply disk 5; Rotating disk 3 drives supply disk 5 together around the glass fiber bundle rotation when rotating like the direction of arrow among Fig. 1, the plastic tape on the supply disk 58 is wrapped on the glass fiber bundle.In order to guarantee winding mass, the present invention has adopted following technological means:
1, adopts supply disk with damping action.
Supply disk with damping action is freely to rotate, and needs certain pulling force to rotate.Can make like this to have certain tensile force when twining, with the flatness that guarantees to twine.Therefore, supply disk 5 adopts the supply disk 5 with damping force, and the supply disk 5 with damping force can be on supply disk, to install rotary damper additional to constitute.Can select the damping torque of 0.1～0.5Kg.cm for use, can not surpass above-mentioned value range, too big plastic tape is broken easily, and the too for a short time plastic tape that is wrapped on the glass fiber bundle is too loose, when moulding, is easy to generate wrinkle, influences fineness.
2, the winding direction of plastic tape is consistent with the winding direction of moulding silk.
Because being the moulding silk that twines above that, the screw thread on the anchor pole reins in out.There is bigger friction between moulding silk and the anchor pole, if the winding direction of winding direction and the moulding silk of plastic tape on glass fiber bundle is inconsistent.When the moulding silk was reined in thread groove on glass fiber bundle, the frictional force direction that the moulding silk produces was opposite with the plastic tape direction of rotation, was easy to make the plastic tape that is wrapped on the glass fiber bundle loose or plastic tape broken, and caused quality problems.
3, supply disk is obliquely installed.
In order to prevent that the resin on the glass fiber bundle from not escaping, be wrapped on the glass fiber bundle plastic tape should before the imbricate of edge and back circle of circle.Because glass fiber bundle is constantly to move backward under the effect of hauling machine; Even the axis normal setting (not tilting) of the axis of supply disk and glass fiber bundle; Also can not be overlapping fully when plastic tape is wrapped on the glass fiber bundle; Also can form spiral and twine, but may cause the lap between the two layers of plastic band excessive, cause the waste of plastic tape.Therefore the present invention is that 30～60 degree are provided with the axis downward projection angle of the axis of supply disk and glass fiber bundle, has with the edge of assurance two layers of plastic band that 1～5mm's is overlapping.
Because method of the present invention is to twine one deck plastic tape in the glass fiber bundle outside that is soaked with resin; Not only improved the fineness on glass fibre reinforced plastics rockbolts surface; Also having avoided resin in forming process, to escape drops on the heater; Resin can send pernicious gas when burning, contaminated air influences the healthy of workman.Obtained minimizing air-polluting windfall effect.
